High-voltage weak-current voltage reducing and current increasing apparatus

The invention relates to a high-voltage weak-current voltage reducing and current increasing apparatus which comprises a front energy buffering unit, a self-adaptive high-frequency high-voltage switching unit and a pulse high-frequency transformer unit, wherein the signal input end of the front energy buffering unit is connected with a high voltage which needs to be reduced; the signal acquisition input end of the self-adaptive high-frequency high-voltage switching unit is connected with the signal output end of the front energy buffering unit; the signal input end of the pulse high-frequency transformer unit is connected with the signal output end of the self-adaptive high-frequency high-voltage switching unit; and the signal output end of the pulse high-frequency transformer unit outputs a final voltage, which is obtained after conversion, by an active supplementing capacitance pool unit for providing an active compensatory stable output for the high-voltage weak-current voltage reducing and current increasing apparatus. According to the high-voltage weak-current voltage reducing and current increasing apparatus, a weak current at the level of below 10mA can be converted, the problem of magnetic eddy current loss is solved, and the effect of final current conversion is ensured. The high-voltage weak-current voltage reducing and current increasing apparatus is applicable to convert a random high-voltage weak-current power supply at the level of over 10kV and below 10mA.
